Philadelphia’s overtime victory over L.A. Wednesday night and the late injury of 76ers player Aaron McKie factored into NBC’s decision to cancel a promised post-game clip of Bono and U2 performing in concert on sister network CNBC.

Simply put, NBC ran out of time.

NBC did show U2 several times during halftime of Game 1 singing such hits as “Where the Streets Have No Name,” “Desire” and “Elevation.”

NBC promised viewers who tuned into the post-game coverage on CNBC that it would show an additional (taped) song, “Beautiful Day” – but that never happened.

Says an NBC Sports spokeswoman: “Wednesday night was a classic NBA finals game, and the breaking updates about [McKie’s] injury took precedence in our post game show and we weren’t able to get to the taped footage of the [U2] concert.”

Game 1 notched 12.4 million households – an 18 percent improvement over last year’s Game 1 (Indiana at L.A.).

Just call him ‘President’ Povich

Talk show host Maury Povich is the new president of the New York Chapter of The National Academy of Television Arts & Sciences (NATAS), succeeding Ch. 13 president Bill Baker.

Povich, elected by the NATAS Board of Governors, will serve a two-year term.

“I have been a member of NATAS for nearly a decade and have found it to be extremely rewarding,” Povich says. “I am very excited of having become the president of the New York chapter of this prestigious organization and am honored to be following in the footsteps of Bill Baker, who is truly one of the class acts of this business.”

Richards scratches itch for ‘Charmed’ role

Scratch Denise Richards off the list of potential Shannen Doherty replacements on “Charmed.”

Sources say Richards, who was being eyed by “Charmed” producers – along with Rose McGowan – has pulled herself out of the running to replace Doherty, who quit the show last month apparently over difficulties with co-star Alyssa Milano.

No word on how far talks have gone with McGowan.

This just in . . .

PBS is moving “Masterpiece Theatre” to Mondays at 9 p.m. beginning this fall. The show had aired Sundays at 9 p.m. for 30 years. “American Masters” will now air Sundays at 9.
